We will switch gears from the cloud tier and focus on Tier 1 and Tier 2, that is, the device and the gateway and how we can build reliability into these key components of the IIoT architecture.
The art of building a fault-tolerant IIoT device and edge gateway
Designing for reliability at the sensors and devices
The main pain point for the device is the ability to communicate reliably to the gateway or to the cloud and send the sensor data in a secure way. The reliability of communications can be attributed to the performance of a few critical components: a radio transceiver and communications microcontroller as part of the device. Wireless connectivity technologies utilized by consumer devices do not always satisfy the greater...
